`dir_info_status` is used from main.c:directory_info_has_arrived() to
provide useful (INFO/NOTICE) level logging to users, and should always
be updated regardless of the rate limiting.
__libc_message() tries to open /dev/tty with O_RDWR, but the sandbox
catches that and calls it a crash. Instead, I'm making the sandbox
setenv LIBC_FATAL_STDERR_, so that glibc uses stderr instead.
Fix for 14759, bugfix on 0.2.5.1-alpha
They have been off-by-default since 0.2.5 and nobody has complained. :)
Also remove the buf_shrink() function, which hasn't done anything
since we first stopped using contiguous memory to store buffers.
Closes ticket 14848.
If the guard unreachable_since variable was set, the status "up" was
reported which is wrong. This adds the "down" status followed by the
unreachable_since time value.

This both fixes the problem, and ensures that forgetting to update
domain_list in the future will trigger the bug codepath instead of
a NULL pointer deref.
After connectivity problems, only try connecting to bridges which
are currently configured; don't mark bridges which we previously
used but are no longer configured. Fixes 14216. Reported by
and fix provided by arma.
If the returned value of read/recv is 0 (meaning EOF), we'll end up in an
infinite loop (active wait) until something is written on the pipe which is
not really what we want here especially because those functions are called
from the main thread.

Once a NACK is received on the intro circuit, tor tries an other usable one
by extending the current circuit to it. If no more intro points are usable,
now close the circuit. Also, it's reason is changed before closing it so we
don't report again an intro point failure and trigger an extra HS fetch.
Fixes#14224

This fixes a bug where we'd fetch different replicas of the same
descriptor for a down hidden service over and over, until we got lucky
and fetched the same replica twice in a row.
Fixes bug 14219; bugfix on 0.2.0.10-alpha.
(Patch from Roger; commit message and changes file by Nick.)
We've started to hit the limit here. We introduced the limit in
0.1.2.5-alpha. This fixes bug 14261, but we should have a smarter way
to not actually do the behavior this permits. See #14267 for a ticket
about fixing that.
The trick here is to apply mapaddress first, and only then apply
automapping. Otherwise, the automap checks don't get done.
Fix for bug 7555; bugfix on all versions of Tor supporting both
MapAddress and AutoMap.
Check for a missing option value in parse_virtual_addr_network
before asserting on the NULL in tor_addr_parse_mask_ports.
This avoids crashing on torrc lines like Vi[rtualAddrNetworkIPv[4|6]]
when no value follows the option.
Bugfix on 0.2.3 (de4cc126cb on 24 November 2012), fixes#14142.
Drop the MIN_REND_INITIAL_POST_DELAY on a testing network to 5 seconds,
but keep the default at 30 seconds.
Reduces the hidden service bootstrap to 25 seconds from around 45 seconds.
Change the default src/test/test-network.sh delay to 25 seconds.
Closes ticket 13401.
TestingDirAuthVoteHSDir ensures that authorities vote the HSDir flag
for the listed relays regardless of uptime or ORPort connectivity.
Respects the value of VoteOnHidServDirectoriesV2.
Partial fix for bug 14067.
Check that tor generates new keys, and overwrites the empty key files.
Test that tor generates new keys when keys are missing (existing
behaviour).
Test that tor does not overwrite key files that already contain data
(existing behaviour).
Tests fixes to bug 13111.
Fixes bug 11454, where we would keep around a superseded descriptor
if the descriptor replacing it wasn't at least a week later. Bugfix
on 0.2.1.8-alpha.
Fixes bug 11457, where a certificate with a publication time in the
future could make us discard existing (and subsequent!) certificates
with correct publication times. Bugfix on 0.2.0.3-alpha.
Also, avoid crashing when we attempt to double-remove an edge
connection from the DNS resolver: just log a bug warning instead.
Fixes bug 14129. Bugfix on 0d20fee2fb, which was in 0.0.7rc1.
jowr found the bug. cypherpunks wrote the fix. I added the log
message and removed the assert.
"Maybe this time should be reduced, since we are considering
guard-related changes as quite important? It would be a pity to
settle on a guard node, then close the Tor client fast and lose that
information."
Closes 12485.
If we decide not to use a new guard because we want to retry older
guards, only close the locally-originating circuits passing through
that guard. Previously we would close all the circuits.
Fixes bug 9819; bugfix on 0.2.1.1-alpha. Reported by "skruffy".
Have clients and authorities both have new behavior, since the
fix for bug 11243 has gone in. But make clients still accept
accept old bogus HSDir descriptors, to avoid fingerprinting trickery.
Fixes bug 9286.
In systemd 209, they deprecated -lsystemd-daemon in favor of
-lsystemd. So we'd better actually look at the pkg-config output,
or we'll get warnings on newer distributions.
For some as-yet-unknown-to-me reason, setting CFLAGS so early makes
it so -O2 -g doesn't get added to it later. So, adding it myself
later. Perhaps a better fix here can be found.
Fixes 14072; bugfix on 0.2.6.2-alpha. Based on a patch from h.venev
We had a check to block these, but the patch we merged as a1c1fc72
broke this check by making them absolute on demand every time we
opened them. That's not so great though. Instead, we should make them
absolute on startup, and not let them change after that.
Fixes bug 13397; bugfix on 0.2.3.11-alpha.
This happened because we changed AutomapHostsSuffixes to replace "."
with "", since a suffix of "" means "match everything." But our
option handling code for CSV options likes to remove empty entries
when it re-parses stuff.
Instead, let "." remain ".", and treat it specially when we're
checking for a match.
Fixes bug 12509; bugfix on 0.2.0.1-alpha.
This allows hidden services to disable the anti-scanning feature
introduced in 0.2.6.2-alpha. With this option not set, a connection
to an unlisted port closes the circuit. With this option set, only
a RELAY_DONE cell is sent.
Closes ticket #14084.
Stop assuming that private addresses are local when checking
reachability in a TestingTorNetwork. Instead, when testing, assume
all OR connections are remote. (This is necessary due to many test
scenarios running all nodes on localhost.)
This assists in bootstrapping a testing Tor network.
Fixes bugs 13718 & 13924.
If the consensus does not contain Exits, Tor will only build internal
circuits. In this case, relevant statuses will contain the word "internal"
as indicated in the Tor control-spec.txt. When bootstrap completes,
Tor will be ready to handle an application requesting an internal
circuit to hidden services at ".onion" addresses.
If a future consensus contains Exits, exit circuits may become available.
Tor already notifies the user at "notice" level if they have no exits in
the consensus, and can therefor only build internal paths.
Consequential change from #13718.
Tor can now build circuits from a consensus with no exits.
But if it tries to build exit circuits, they fail and flood the logs.
The circuit types in the Exit Circuits list below will only be
built if the current consensus has exits. If it doesn't,
only the Internal Circuits will be built. (This can change
with each new consensus.)
Fixes bug #13814, causes fewer path failures due to #13817.
Exit Circuits:
Predicted Exit Circuits
User Traffic Circuits
Most AP Streams
Circuits Marked Exit
Build Timeout Circuits (with exits)
Internal Circuits:
Hidden Service Server Circuits
Hidden Service Client Circuits
Hidden Service AP Streams
Hidden Service Intro Point Streams
Circuits Marked Internal
Build Timeout Circuits (with no exits)
Other Circuits?
If the consensus has no exits (typical of a bootstrapping
test network), allow tor to build circuits once enough
descriptors have been downloaded.
When there are no exits, we always have "enough"
exit descriptors. (We treat the proportion of available
exit descriptors as 100%.)
This assists in bootstrapping a testing Tor network.
Fixes bug 13718.
Makes bug 13161's TestingDirAuthVoteExit non-essential.
(But still useful for speeding up a bootstrap.)
Add router_have_consensus_path() which reports whether
the consensus has exit paths, internal paths, or whether it
just doesn't know.
Used by #13718 and #13814.
count_usable_descriptors now uses named exit_only values:
USABLE_DESCRIPTOR_ALL
USABLE_DESCRIPTOR_EXIT_ONLY
Add debug logging code for descriptor counts.
This (hopefully) resolves nickm's request in bug 13718 to improve
argument readability in nodelist.c.
choose_good_entry_server() now excludes current entry
guards and their families, unless we're in a test network,
and excluding guards would exclude all nodes.
This typically occurs in incredibly small tor networks,
and those using TestingAuthVoteGuard *
This is an incomplete fix, but is no worse than the previous
behaviour, and only applies to minimal, testing tor networks
(so it's no less secure).
Discovered as part of #13718.
